IPC: B02C23/18
Filed: 1996-01-12
Abstract: PROBLEM TO BE SOLVED: To easily dissociate fine particles and reuse them as a placing powder by dissociating fine particles stuck or welded with each other by suction at the time of producing the fine particles through reaction, melting, etc. SOLUTION: In a stage in which the fine particles such as spherical ceramics are produced by reaction, melting or burning or the stage in which the particles are used as the placing powder at a high temp., particles are stuck or welded in aggregation, continuous chain and satellite-like with each other. At that time, the fine particles stuck or welded with each other are dissociated when a pipe is inserted into a vessel in which the fine particles are put and by sucking the vessel with a sucking type blast equipment for projection, and the particles are suck by pulling an air valve and sprayed from the injection nozzle at a tip of a gun to recover the particles.

IPC: B21B1/22
Filed: 1983-01-13
Abstract: PURPOSE:To perform the rollings of width spreading, loose structure squeezing, and thickness reducing by a single rolling mill, by incorporating two pairs of work rolls containing >=1 pair of rolling reduction rolls for local parts, between a pair of rolls, in performing rolling. CONSTITUTION:In a rolling mill of a plate material 10 provided with two pairs of work rolls 4A, 4A, 4B, 4B to the space between a pair of rolls 2, 2, the rolls 4A, 4A are used as the rolling reduction rolls for local parts, for instance. That is, a local rolling reduction ring 8 is movably attached to a moving service shaft 6 of the rolls 4A, 4A. When a loose structure squeezing is mainly performed for instance, the central part in the width direction is intensely subjected to rolling reduction by the local rolling reduction rolls 4A, 4A, and the rolling parts at both side ends of the material 10 are successively subjected to rolling reduction by the same amount of rolling reduction by means of the flat rolls 4B, 4B located at the outlet side; thus the loose structure squeezing and the thickness reduction are performed by one pass.

Title: Liquid seal type vibration damping roll
Inventor: TAKENAKA YOSHIYUKI
IPC: F16C13/00
Filed: 1983-01-13
Abstract: PURPOSE:To always maintain a constant fluid pressure and improve vibration damping performance by fixing a container to the end face of a roll body and putting its liquid chamber in communication with a gap part of the roll body and further providing the liquid chamber with a means to change its capacity. CONSTITUTION:Both ends of an inner cylinder 1 are joined to shaft end parts 5, while the inner cylinder 1 is wrapped in an outer cylinder 2. In this case, an appropriate number of liaison holes 7 piercing outward are drilled in the end face of the inner cylinder 1. Further, a container 8 with an annular countersunk part 15 is bolted 9 on the end face of the cylinder 1. Then a ring-shaped piston 10 is contained in the countersunk part 15 of the container 8 and supported by means of an elastic body 11. When fluid is sent into a gap part 14 between the inner cylinder 1 and the outer cylinder 2, the fluid fills a space 15a between the container 8 and the piston 10 through the liaison holes 7, and the piston 10 stops in a position where spring tension of the elastic body 11 is balanced with the pressure of the fluid. Accordingly, constant fluid pressure can be always maintained, and vibration damping performance can be improved.

IPC: B01J4/00
Filed: 1986-01-10
Abstract: PURPOSE:To obtain the title apparatus especially suitable for a gypsum stock material having strong adhesiveness, in an apparatus for discharging a powder in a send storage tank from a first storage cylinder, an opening and closing cylinder and a cylinder apparatus. CONSTITUTION:For example, in the gypsum stock material discharge apparatus of gypsum baking equipment, at first, a cylinder apparatus 1 is operated and an opening and closing plate 9 is shaken to an open position. Subsequently, the stirring blade in a supply tank 1 is rotated to discharge a gypsum stock material to the tank main body 4 of an intermediate tank 2 from a discharge port 3 and the opening and closing plate 9 is subsequently closed. At this time, because the opening and closing plate 9 is set to a size so as to be freely engaged with and detached from the discharge port 3, even if the gypsum stock material is adhered to the periphery of the opening and closing plate 9, the adhered stock material is released by the operation of the opening and closing plate itself. AT the open position of the opening and closing plate 9, because the lower end thereof is positioned in the tank main body 4 wider than a connection cylinder 5, the gypsum stock material is not accumulated on the inner wall surface of the connection cylinder 5 in the back surface side of the opening and closing plate 9 and opening and closing operation can be smoothly performed.

Title: Dc machine and dc motor device
Inventor: OHARAGI HARUO
IPC: H02P7/06
Filed: 1989-01-13
Abstract: PURPOSE:To compensate non-spark zone moving phenomenon and to prevent a brush from causing the spark by strengthening field magnetomotive force larger than the commutating pole magnetomotive force in a base rotating speed and by weakening the former than the latter. CONSTITUTION:In reinforced field system (in a base rotating speed), leakage flux phiLP going through a magnetic bridge 10A is utilized as commutating pole flux quantity. In weak field system (in a maximum rotation speed), a part of the flux phiIP3 of the commutating pole flux phiZP going through the magnetic bridge 10A is utilized as the main flux phiMP. Thus, the commutating flux quantity from the tip of a commutating pole core 8 to an armature can be changed drastically in the reinforced field system and in the weakened field system. As a result, the commutating pole flux quantity in the maximum rotating speed can remarkably be reduced against the commutating pole flux quantity in the base rotating speed. This moving phenomenon of non-spark zone in a DC machine can thereby be compensated and the occurrence of spark from a brush can be prevented.
